    :captain: The only solution to solve broadcast problems is to breakup the exiting network or a single broadcast domain in to multiple smaller broadcast domains called as VLAN. A virtual LAN is a logical grouping of network devices in the same broadcast domain that can span multiple physical segments. All device connected to the hub are in the same collision domain but layer 2 switches network create individual collision domain for each device plugged into each port on the switch.

    A VLAN can be defined as a virtual broadcast domain instead of segmenting the broadcast domain with router at layer-3; you segment using switches at layer-2. Logically speaking, VLANs are also subnets. A subnet or a network is a contained broadcast domain. A broadcast that occurs in one subnet will not be forward by default to another subnet. You can add 500 computers in a single broadcast domain. VLAN contain broadcast traffic, where you need a router to move traffic between VLAN.

    So, what's the challenge? I don't see any question there. Besides, might I say that VLAN is not the only solution for solving the broadcast problems.
